A salmonella scare has forced Mars Petcare US to recall 100 of its 20-pound bags of PEDIGREE Complete Nutrition Small Crunchy Bites sold at some Albertsons in Southern California and Las Vegas, Nevada.

The company also makes Nutro pet food, which scores of consumers nationwide blame for the recent illnesses – and even deaths – of their dog and cats.

Nutro products, however, are not included in this recall.

Mars said a “component” that tested positive for salmonella was inadvertently shipped to its Tracy, California, plant and used in the production of 100 bags of PEDIGREE pet food.

The affected bags have the “best by” dates of July 7, 2009.

“Our primary concern is the safety and welfare of our pet owners and their pets,” the company said in a statement. “Although the finished product tested negative and we have received no reports of illness of pets or their owners, out of an abundance of caution we are issuing a voluntary recall of the limited number of bags of Pedigree Complete Nutrition Small Crunchy Bites containing the component in question.”

The following are tips to help prevent the spread of salmonella poisoning.

Salmonella can cause infections in dogs and cats. It can also be transferred from pets to people who ingest or handle contaminated products. Children, the elderly, and those with compromised immune systems are most at risk.

To prevent the spread of salmonella contamination, the FDA said consumers should wash their hands for 20 seconds with hot water and soap before and after handling pet foods and treats.

Consumers should also: Wash pet food bowls, dishes, and scooping utensils with soap and hot water after each use;

Not use their pets’ feeding bowl as a scooping utensil. Pet owners should use a clean scoop or spoon;

Dispose of old or spoiled pet food products in securely tied plastic bags and put them in a covered trash cans.
